I saw someone trying to talk about the experimental menu and how it can be used to turn on a sega saturn emulator. Where is this experimentals menu? Also, to run .mdf roms you must edit es_systems.cfg, where is es_systems.cfg located?
Depends on what version of retropie you’re using. Newer ones have a retropie menu in emulationstation with an option to get into the retropie setup script. In the setup script option 4 is the experimental menu (if you don’t have an RPI 2 the Sega Saturn isn’t going to work at all and even with a rpi2 it still barely even functions if at all) https://github.com/RetroPie/RetroPie-Setup/wiki/Saturn
If you have an older build you can access the setup script from the terminal
es_systems.cfg is located at /etc/emulationstation/es_systems.cfg
Yes if you’ve updated your setup script you can install them through the experimental menu and virtual boy and neogeopocket will have a theme. I can’t remember if wonderswan did or not. See the wiki for which ROM folders you’ll place your ROMs in and what extensions you’ll need:
In the retropie setup script there is an option to “update the setup script” so in order to update it, you select that option. Then you’ll exit out of the setup script and go back in so that the changes are saved and then you can navigate to the experimental menu and install your emulators.
What updating the setup script does is just grabs the latest scripts from github so that all the changes since the SD image was built are available.
